A multifunctional pen includes a penholder and a refill provided in the penholder. A clip is provided on the penholder. The penholder comprises an upper penholder and a lower penholder hinged to each other. The lower penholder may bend and tilt toward the upper penholder through a hinged joint. The clip is arranged on the upper penholder and across the upper penholder and the lower penholder. A tail end of the clip is raised and a pressing raised strips for a mobile phone is provided thereon.

A clip comprised of removably attached components. The clip may be attached to a writing instrument, such as a pencil, or stylus. The surface of the clip has male elements that allow the components to snap on to the clip so that the clip may be adorned. The components are secured to the clip so that they may rotate freely around the male element. The components may be comprised of decorative elements, such as jewels, initials, logos, or pictures. The components may be comprised of a utilitarian element, such as a lanyard, or a flashing light to indicate an incoming email. The components may have a tactile surface comprised of bumps, or waves. The components may comprise of movable elements such as a rolling ball, or star that spins. The tactile surface and moving elements of a component may aid in the treatment of anxiety and attention deficit disorders.
